i made an alpha pattern which was too long so i made it in 2 separate parts, and i want to add the second part in the "similar patterns" box but i keep getting this error "Please write the similar patterns on the correct form, for example "1,2,3"

... can someone plz explain?:(

nvm i found out, when adding i always put the A b4 the numbers i tought that makes part of the pattern but when i erased the A it worked:) tks anyway for anyone who would have tried to help^^ lol:))
